The new Pro2 is 8BitDo’s most powerful bluetooth game controller yet. They added a pair of Pro back buttons to keep your thumbs in play at all times. Another sweet feature allows you to toggle through 3 preset player profiles. Mode Switch allows users to easily swap from one mode, like Switch, to Android mode without a restart. It runs the brand’s Ultimate Software through the Pro2 app which allows you to customize, map & re-map the buttons & functions as needed.
